ABSTRACT:
A crank handle assembly for mounting onto an end of a rotatable shaft of a window moving or carriage mechanism for raising and lowering a window of a vehicle such as an automobile or truck. The assembly includes a crank arm having at one end a head for engaging the carriage mechanism shaft and at the other end a knob base with an integral circular knob extending therefrom. The knob has an outwardly extending side surface and an end surface, the side surface being separated from the knob base by a groove forming a rounded shoulder facing the crank arm. A cylindrical cap or handle of resilient plastic material for fitting onto the knob includes an open end, a side wall and a closed end wall defining a well for receiving the knob. The open end has an inwardly extending annular ring or flange for positioning with the groove and engaging the shoulder. The cap is sized so that the closed end wall, the side wall and the ring engages corresponding portions of the knob and thereby effect a secure, wobble-free rotative connection for gripping the cap and rotating the crank arm.
